In the videos, Swift is seen "battling" her younger brother, Austin, with Easter eggs. It seems as though they play a game where each sibling holds an Easter egg in one hand (clearly pre-decorated by the Swift siblings) and, on the count of "three," they put their game faces on and stare into each other's eyes until one of them is brave enough to smash their egg into the other's. Whoever is holding the egg that breaks, loses.
